1. Blair Bridge Marker
Inscription. Hiram W. Merrill (1822-1898) of Plymouth, N. H., built this bridge in 1870 to replace a span of 1829 that had been burned by an arsonist. The bridge employs a truss design patented by Col. Stephen Harriman Long (1784-1864) of Hopkinton, N. H. It is New Hampshire's only surviving example of Long's patent to retain wedges at the lower chords by which the trusses were pre-stressed during construction, stiffening the bridge against the weight of traffic. Covered bridge expert Milton S. Graton (1908-1994) restored the structure in 1977.

Lem Parker who claimed that God told him to do it. Parker was taken to court and confessed to the charges. However, he was found not guilty because there were no witnesses. The construction of the current bridge was brought about when a doctor trying to ford the river on horseback found the current too strong. The horse drowned, but the doctor was saved. The town voted to build a bridge immediately. A sign was posted on the bridge indicating there was a fine of five dollars for riding or driving on the bridge faster than five miles per hour. It was rebuilt by Milton Graton and his son Arnold in 1977 at a cost of $59,379. The town of Campton and the state shared the cost of the repair. The Blair Bridge is eligible for listing on the National Register of Historic Places.
